Description

Technical Field

[0001] The utility model belongs to the technical field of litz wires, and in particular relates to an oxidized insulated high-conductivity shaped litz wire. Background Art

[0002] Currently, Litz wire is mainly used in the high-frequency transformer industry and the inductive wireless charging industry. Among them, the high-frequency transformer product in the electronics industry is a traditional electronic device. The electromagnetic wire products or Litz wire products currently used are all pure copper wires, which are high in cost, heavy in weight, and have low high-frequency conductivity.

[0003] However, during the setting process of the existing oxidized insulated high-conductivity shaped Litz wire, although an insulating layer is provided between the wire bundles, the middle inner area of ​​the Litz wire body is not breathable because it is in a sealed state. When the Litz wire body is overheated, it has no heat dissipation properties and is therefore prone to damage.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] An oxidized insulated, highly conductive, shaped Litz wire comprises a Litz wire body, wherein an inner cavity of the Litz wire body is provided with a first copper oxide wire, an outer wall of the first copper oxide wire is provided with a first insulating layer, and an outer wall of the first insulating layer is provided with a plurality of circumferentially distributed second insulating layers, each of the second insulating layers having an inner cavity wrapped with a second copper oxide wire, and the outer wall of each second insulating layer is adhered to the inner wall of the Litz wire body. The inner cavity of the Litz wire body is provided with insulating materials on the outer walls of the plurality of second insulating layers and the first insulating layer, each of the insulating materials being circumferentially distributed. Because the insulating materials are provided with first and second through-holes, and the first and second through-holes are respectively penetrated by connecting through-holes and connecting through-holes, the connecting through-holes and connecting through-holes respectively penetrate the first and second insulating layers, allowing the first and second insulating layers to communicate with the first and second through-holes, respectively, through the connecting through-holes and connecting through-holes, thereby enabling connection to the outside world, thereby ensuring that the first and second copper oxide wires within the Litz wire body can dissipate heat when heated.

[0007] As a preferred embodiment of the present invention, each of the insulating objects is provided with a first through hole and a second through hole, thereby ensuring that the first through hole and the second through hole can be in contact with the outside world.

[0008] As a preferred embodiment of the present invention, each of the first and second through-holes has a connecting through-hole formed in the insulator, and each of the connecting through-holes extends through the sidewall of the first insulating layer. Because the insulator has the first and second through-holes, and the first and second through-holes each have a connecting through-hole, the connecting through-holes extend through the first insulating layer, allowing the first insulating layer to communicate with the first through-holes through the connecting through-holes, thereby enabling connection to the outside world. This ensures that the first copper oxide wire within the Litz wire body can dissipate heat when heated.

[0009] As a preferred embodiment of the present invention, each of the connecting through-holes is provided with a connecting through-hole through the insulating material, and each of the connecting through-holes extends through two adjacent second insulating layers. Because the insulating material is provided with a first through-hole and a second through-hole, and the first through-hole and the second through-hole are respectively provided with connecting through-holes, the connecting through-holes extend through the second insulating layers, allowing the second insulating layers to communicate with the outside world through the connecting through-holes. This ensures that the second copper oxide wire within the Litz wire body can dissipate heat when heated.

[0010] As a preferred embodiment of the present invention, the surface of the Litz wire body is covered with a rubber insulating material, which has good heat resistance and aging resistance.

[0011] As a preferred embodiment of the present invention, the first copper oxide wire and each second copper oxide wire are made of dicumyl peroxide material, and dicumyl peroxide has a strong insulation function.

[0012] As a preferred embodiment of the present invention, the insulation is made of polyvinyl chloride material, and has good mechanical properties, chemical corrosion resistance, no flame retardancy, good weather resistance, good electrical insulation performance, and easy processing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] According to the present invention, the first through hole and the second through hole are provided on the insulating material, and the first through hole and the second through hole are respectively penetrated by the connecting through hole and the connecting through hole. Therefore, the connecting through hole and the connecting through hole respectively penetrate the first insulating layer and the second insulating layer, so that the first insulating layer and the second insulating layer can be connected to the first through hole and the second through hole respectively through the connecting through hole and the connecting through hole, and thus can be connected to the outside world, thereby ensuring that the first copper oxide wire and the second copper oxide wire in the Litz wire body can dissipate heat when heated.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0023] like Figures 1 to 4 As shown, the oxidized insulated high-conductivity shaped Litz wire includes a Litz wire body 1, an inner cavity of the Litz wire body 1 is provided with a first copper oxide wire 2, an outer wall of the first copper oxide wire 2 is provided with a first insulating layer 5, and an outer wall of the first insulating layer 5 is provided with a plurality of second insulating layers 4 distributed in a circumferential manner. The inner cavity of each second insulating layer 4 is wrapped with a second copper oxide wire 3, and the outer wall of each second insulating layer 4 is fitted and connected to the inner wall of the Litz wire body 1. The inner cavity of the Litz wire body 1 is provided with insulating materials 6 on the outer walls of the plurality of second insulating layers 4 and the first insulating layer 5, and each insulating material 6 is distributed in a circumferential manner. Because the insulator 6 is provided with a first through hole 7 and a second through hole 8, and the first through hole 7 and the second through hole 8 are respectively penetrated by a connecting through hole 9 and a connecting through hole 10, the connecting through hole 9 and the connecting through hole 10 respectively penetrate the first insulating layer 5 and the second insulating layer 4, so that the first insulating layer 5 and the second insulating layer 4 can be connected to the first through hole 7 and the second through hole 8 through the connecting through hole 9 and the connecting through hole 10 respectively, and thus can be connected to the outside world, thereby ensuring that the first copper oxide wire 2 and the second copper oxide wire 3 in the Litz wire body 1 can dissipate heat when heated.

[0024] In a specific embodiment, each insulator 6 is provided with a first through hole 7 and a second through hole 8. In this configuration, the positions of the first through hole 7 and the second through hole 8 are determined to ensure that the first through hole 7 and the second through hole 8 can contact the outside world.

[0025] Furthermore, each of the first through-holes 7 and the second through-holes 8 is provided with a connecting through-hole 9 in the insulator 6, and each connecting through-hole 9 extends through the side wall of the first insulating layer 5. In this arrangement, because the insulator 6 is provided with the first through-holes 7 and the second through-holes 8 are each provided with a connecting through-hole 9, the connecting through-holes 9 extend through the first insulating layer 5. This allows the first insulating layer 5 to communicate with the first through-holes 7 through the connecting through-holes 9, thereby enabling connection to the outside world. This ensures that the first copper oxide wire 2 in the Litz wire body 1 can dissipate heat when heated.

[0026] Furthermore, each connecting through-hole 9 is provided with a connecting through-hole 10 on the insulating material 6, and each connecting through-hole 10 extends through two adjacent second insulating layers 4. In this arrangement, because the insulating material 6 is provided with a first through-hole 7 and a second through-hole 8, and the first through-hole 7 and the second through-hole 8 are respectively provided with a connecting through-hole 10, the connecting through-hole 10 extends through the second insulating layer 4. This allows the interior of the second insulating layer 4 to communicate with the second through-hole 8 through the connecting through-hole 10, thereby enabling connection to the outside world. This ensures that the second copper oxide wire 3 within the Litz wire body 1 can dissipate heat when heated.

[0027] Furthermore, the surface of the Litz wire body is covered with a rubber insulating material, which has good heat resistance and aging resistance; the first copper oxide wire and each second copper oxide wire are made of dicumyl peroxide material, and dicumyl peroxide has a strong insulating function; the insulation is made of polyvinyl chloride material, and has good mechanical properties, chemical corrosion resistance, no flame retardancy, good weather resistance, good electrical insulation performance, easy processing, etc.

[0028] The implementation principle of the oxidized insulated high-conductivity shaped Litz wire of this embodiment is as follows: first, the first copper oxide wire 2 and the plurality of second copper oxide wires 3 are respectively installed in the first insulating layer 5 and the plurality of second insulating layers 5. After the first insulating layer 5 and the plurality of second insulating layers 5 are installed in the inner cavity of the Litz wire body 1, the staff will install the insulation 6 at this time. When the installation is completed, because the first through hole 7 and the second through hole 8 are opened on the insulation 6, and the first through hole 7 and the second through hole 8 are respectively penetrated by the connecting through hole 9 and the connecting through hole 10, the connecting through hole 9 and the connecting through hole 10 are respectively penetrated through the first insulating layer 5 and the second insulating layer 4, so that the first insulating layer 5 and the second insulating layer 4 can be connected to the first through hole 7 and the second through hole 8 through the connecting through hole 9 and the connecting through hole 10 respectively, so that they can be connected to the outside world, thereby ensuring that the first copper oxide wire 2 and the second copper oxide wire 3 in the Litz wire body 1 can dissipate heat when heated.
